libertas: command 1f timed out error

[Ram kumar]

hi,
       When i connect my SDIO wireless module to my eval kit at91sam9260,

The marvel 8686 SDIO module is not able to get a ip address from my
Access point through DHCP.

Whereas the same marvell 8686 SDIO module is able to set static ip
through the Access point.

when i type

# dhclient eth1

 this is my output...

I dont know why this is happening....Is it because of the marvell
firmware doesn't support some commands sent by the libertas driver
????

Initially when i load the libertas driver,i get some error
message....like this...I guess it is related to some Mesh function....

# modprobe at91_mci
mmc0: new SDIO card at address 0001
# modprobe libertas_sdio

Is it becuase of these command failure the module is not able to get a
DHCP address from AP ????

Here is output of iwconfig and ifconfig for my module.....

I have applied this libertas patch in order to ease the firmware download.....

Is it because of this patch the module is not able to get a ipaddress
from the DHCP of the AP ????

My /etc/dhcp/dhclient.conf file has the following contents....

request subnet-mask, broadcast-address, time-offset, routers,
	domain-name, domain-name-servers, host-name,
	netbios-name-servers, netbios-scope;

Do i have to add anything in this file(dhclient.conf) in order to get
the ipaddress from the DHCP of the AP ???

Please guide me....to overcome this error ????...

Please tell me whether it is because of the firmware or the libertas
driver or because of the poor configuration of the dhclient ??

If there is any patch or some other marvell firmware to overcome this
error....Please refer me the link ????

Ram
